Bug: Why is core useage for optimization limited to 64 cores only?
17 Jan 2024, 12:42

I am using a Windows computer with an AMD Ryzen Threadripper CPU with 64 physical and 128 logical Cores, see below.

While running optimizations, I put the CPU usage slider to 100%. However, only 64 of 128 cores are being used, see below.

The reason cannot be because of cTrader not using logical cores, because on a CPU with 16 physical and 32 logical cores, ALL cores are used by cTrader, see below.

Why is cTrader limiting the number of cores being used to max 64?

 

============ CPU with 128 cores ===========

===============================================================================

==============  Intel Xeon CPU with 16 phys cores ======

Hi PanagiotisCharalampous,

same here. I rented a 96-Core machine to optimise an algorithm and here I have a usage of ⅓ of the cores. I am able to run 3 instances of CTrader with optimisation running, every instance tests 31 combinations…

Troubleshooting has been submitted.

Best,
